Anavatapta (Sanskrit अनवतप्त "the Unheated", Chinese: 阿那婆達多; pinyin: Ānàpó-dáduō; Japanese pronunciation: Anabadatta, also called Chinese: 無熱(悩)池; pinyin: Wúrènǎochí; Japanese pronunciation: Munetsu(nō)chi "the Pond without Heat") is the lake lying at the center of the world, according to ancient Indian tradition. The name Anavatapta means "heat-free"; the waters of the lake were thought to be able to soothe the fires that torment beings. Anavatapta is also the name of the dragon that was said to live in the lake; having become a bodhisattva, it was free from the distresses that plague other dragons, which are tormented by fiery heat and preyed on by garudas.
